MEASURINGPUMP.

4 SPECIFICATION forming part of Letters Patent No. 480,550, dated August 9, 1892.

Application iiled May 2, 1892. Serial No. 431,416. (No model.)

To all whom it may concern:

Be it known that we, SYLvANUs F. BoWsER and AUGUSTUS BovvsER, citizens of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented certain newand useful Improvements in Measuring-Pumps, (Case B and we do hereby declare the following to be a full, clear, and exact description of the invention, such as Will cnable others skilled in the art to which it appertains to make and use the same.

This invention relates to measuring-instruments, and more especiallyto that class thereof known as measuring-pumps;77 and the object of the saine is to elect certain improvements in the gaging mechanism for controlling the amount of liquid which the pump shall discharge. This object is attained by the mechanism hereinafter more fully described and claimed, and as illustrated in the accompanying drawings, wherein- Figure l is a side elevation of the storagetank, partly in section,to show the contained mechanism in elevation. Fig. 2 is a vertical section of said mechanism. Fig. 3 is a plan view of a portion of the top of the tank. Fig. 4 is a reduced vertical section of a modied form of said mechanism, using a slide on the top of the tank. Fig. 5 is an enlarged plan view of said slide.

In United States Letters Patent No. 372,250, granted to us on October 25, 1887 We employed an oscillatory stop-rod in connection with a plurality of stops thereon and a single collar on the pump-rod. Prior to that patent devices had been patented employing oscillatory pump-rods having radial stops engaging beneath the tank-cover, and also others employing notched pump-rods and slides on the cover whose tips engaged said notches. The present invention is an improvement over all these devices in that it employs an auxiliary rod for the stop-collars, and the collars (and slide when it is used) differ from those hitherto constructed with apparent resultant advantages.

Referring now to the accompanying drawings, the letter A designates a tank, below whose bottom a the pump-cylinder B is preferably located in order that all the liquid within the tank may be drained by this device. Said cylinder is situated within a can C, which communicates with the interior of the tank A at c, and the liquid in the can finds a passage through an upwardly-opening valve V into the. pump-cylind er below its solid head b.

The action of the pump as illustrated, though not material in its construction to the present case, is that when the pump-rod D is forced down the liquid is expelled or forced upward through and out of the delivery-spout J, which leads from within the can, as shown, and passes through the top E of the tank A, as does the rod D, wh ereby it may be operated from the exterior of the tank, all as will be clear.

Coming now to the present invention, the letter F designates a supplemental or gage rod cranked near its ends, so that its body will stand at some distance from yet parallelwith the pump-rod D, said ends embracing said rod and being confined between collars d, which may be provided with set-screws d or other means for rendering them adjustable at times. Thus it will be seen that the gage-rod may swing to acertain extent around the pump- `rod if the latter be cylindrical, or with it if it be angular, and to permit such swinging the top E of the tank is provided with a hole W for the pump-rod and with a curved slot I struck around the hole NV for the gage-rod, and having an extension t' at one extremity, preferably radial to the pump-rod, as seen in Fig. 3. To the gage-rod are secured two collars or stops G and H in any manner, as between nuts N, as seen in Fig. 1,by set-screws N as in Fig. 2, or otherwise, the uppermost one G being radial to the pump-rod and the lowermost one H standing at some angle to the radial line from the pump-rod through the gage-rod. The stop G is of such size that when the gage-rod stands at the proper extremity of the slot I this stop may move upward through the extension t', and the lowermost stop H will strike beneath the top E; but when the gage-rod stands at the opposite extremity of the slot I the uppermost stop G will strike beneath the top E as the rod D is lifted. The two stops being properly set axially to and adjusted longitudinally on the gage-rod and the latter adjusted properly on the pump-rod, it will be clear that the operator may control the degree of rise of the pump-head within its cylinder, and hence of IOO the amount of liquid which is permitted to pass thereinto and be ejected from the spout- J. Thus if the upper stop G strikes the top E the pump will admit and eject one charge, (say one quart but if allowed to pass through the extension z', so that the lower stop H strikes the top E, the pump will admit three charges, (say three quarts.) To deliver two charges, the pump is operated twice at the stop G; three, once at stop H; four, once at each, and so on; or any other arrangement of these stops could be made, perhaps so that they would deliver in fractions of chargesone in pints and the other in quarts, for instance. If the gage-rod turns upon the pumprod, it will be set by hand by the operator. If it is fast thereon, he simply turns the handle of the pump-rod before raising it, all as will be clear.

In Figs. 4 and 5 we have shown a slight modification of the construction described above. In this case the pump-rod is preferably square or angular, though it .may here also be round, so as to turn, and the cover or top E provided with the same curved slot. However, we prefer that the pump-rod, D pass through a square hole in the top E and the gage-rod F pass through a hole I,which is of sufficient size to permit the passage of the stop G', and the stops are so arranged as to project in different radiallines from the gage-rod as above. A slide J is in this case provided, perferably having a slotted body j, which moves under a headed screw j', although any means may be provided for controlling the slide. The tip of the latter is adapted to move over and partially close the hole I', as shown in Fig. 4. In this instance the stop G will strike the slide and one charge only can be ejected. When the slideis retracted, this stop may pass through the hole I', but the stop H will strike beneath the top E', and three charges will be ejected, the operation being substantially the same as above explained, except that the user adjusts the slide instead of the gage-rod. It will be clear this slide may be used in connection with the. curved slot I of Fig. 3 by locating the slide so that it will cover the extension i. Indeed it may in some cases be desirable to provide the device with both forms of gaging mechanism in order that the slide may be thrown into use if the gage-rod should ever stick or become bent so that it will not readily turn within and from end to end of the curved slot I. In this event the extension z' simply takes the place of the hole 1 of Fig. 4, and the device is operative in this way until the tank is empty and can be cleaned again.

The parts are of any desired size, material, and shape, so long as no departure from the spirit of this invention is adopted.

The uses and operation of the whole are well known to those familiar with this class of machines, and we willnot therefore explain it in further detail.

What is claimed as new is Vgage-rod also passing through the tank, its

body standing parallel with the pump-rod and its ends being cranked and connected with said pump-rod, and adjustable collars on the pump-rod against the ends of the gage-rod, substantially as and for the purpose set forth. 2. In a measuring-pump, the combination,
